thomst writes: Science Magazines's Tim Wogan reports that chemical engineer Zhenan Bao of Stanford University in Palo Alto, California, and her team have increased the conductivity of a self-healing polymer by incorporating nickel atoms. The polymer they have produced is sensitive to applied forces like pressure and torsion (twisting) because such forces alter the distance between the nickel atoms, changing the electrical resistance of the polymer. Their work is published online in the November 1 issue of Nature Nanotechnology (abstract here, full article paywalled). Now Bao and her team are working on making the polymer more flexible.
